Superstitions and Old Wives' Tales

Black cats kind of get a bad rap.  According to superstition, you shouldn't cross paths with a black cat. Since today is Halloween, I thought I would bring up the subject of superstitions and old wives' tales.  I had a conversation several weeks ago with Lauren and one of her friends about how a lot of buildings don't have a thirteenth floor.  Next time you are in an elevator of a tall building, look and see if it has a thirteenth floor. What about how you shouldn't walk under a ladder? I asked the hubby about that one and he said something like, "why would you walk under there, it's unsafe!"  True :)  One I remember from my childhood, was don't step on the cracks of the sidewalk - "step on a crack, you'll break your mother's back." Ouch! Another one I have heard FOREVER - don't  go out with a wet head, you'll catch a cold.  I always go outside with a wet head - I have very thick hair and it takes hours to dry - it's already dry enough because I color it, so I don't blow dry very often :)  I have yet to get a cold from going out with a wet head.  If I ever do get sick, I'll try a little chicken soup!!  How about when you're pregnant and you put a needle/ring on a string in front of your belly and if the needle/ring goes a certain way you're having a boy and if it goes another way it's a girl?  There are so many superstitions and old wives' tales still floating around out there!! Don't ever break a mirror - seven years bad luck, an apple a day keeps the doctor away, the list goes on and on and on.  My husband told me that his parents told him growing up if you changed the calendar to the new month before the old month was over, that would bring you bad luck. We still adhere to that one around here, whether I want to or not :)  Maybe I'll go around today and change all of our calendars in the house to November, just to play a little "trick" on my husband!! Two superstitions that bring you good luck are finding a four-leaf clover or picking up a penny.  What are some old wives' tales or superstitions that you believe or don't believe??
